NAME
Data::PowerSet::Hash - Power sets of hashes
VERSION
version 0.03
DESCRIPTION
This provides you with a power set (basically all combinational
iterations) for your hashes. This only does it for hashes, if you want
them done for arrays, I suggest using Data::PowerSet. Please view the
*SEE ALSO* section below.
SUBROUTINES/METHODS
hash_powerset
Create a powerset from hash keys.
use Data::PowerSet::Hash 'hash_powerset';

husband => 'Homer Simpson',
wife => 'Marge Simpson',
);
# @pset = (
# {
# husband => 'Homer Simpson',
# wife => 'Marge Simpson',
# },
# { husband => 'Homer Simpson' },
# { wife => 'Marge Simpson' },
# {},
# )

See documentation for it above.
